they are able to penetrate high threat environments and so that's certainly an area that we are looking at in the near and the long-term. >> let's go to the question of the number of orbits that the air force needs to generate. i know this has been a contention issue over the years but at one point it was to be able to generate 50 orbits and each for remotely piloted airplane craft to generate a 1 aircraft over a particular spot for 24/7 coverage. and then the number went to 65 and you were building 65 and then it was like to be able to surge to 80. that was at the height of the aversion and iraq wars. are these requirements still valid and at what point is the air force going to be told you don't have to build to that. >> i think that will be a dialogue that we have, especially as we build the f515 programs and look at the future and discover what is the footprint in afghanistan, what is the footprint across southwest asia and what do we need for the less permissive environments. the current guidance is 65 with the capability to surge to 85. our budget supports that and by may of 2014
